What is characterized by early mortuary behavior related to the basic rights of all deceased to have a decent burial?

The concept described in the question is best represented by the idea of pagan roots in mortuary behavior. Historically, various pagan cultures emphasized the importance of providing proper burials and honoring the deceased, as this was considered essential for the deceased to find peace and for the living to maintain their connection with their ancestors. This understanding of respect for the dead reflects an early acknowledgment of the basic rights of all individuals, regardless of their background, to a dignified burial.

Pagan traditions often included specific rituals and practices aimed at ensuring that the deceased were treated with reverence. These early customs laid the groundwork for many modern attitudes towards funerary practices, highlighting the fundamental human concern for death and the afterlife.

In contrast, other choices might focus on later developments in burial practices or spiritual beliefs that followed the establishment of organized religions and cultural norms rather than the foundational perspective of honoring the dead as seen in pagan practices.
